Abstract

Wind turbine blade (1) comprising a blade body (2) and lift-regulating means (3, 7) adapted for movement in relation to the blade body (2) by at least one actuation means (4) controlled by an actuation controller (5), wherein the actuation controller (5) controls a setting of the lift-regulating means (3, 7) based on an input from a sensor (6), wherein the sensor (6) is a force sensor adapted for sensing a force from a wind flow acting on the lift-regulating means (3, 7), whereby a wind turbine blade with fast-responding lift-regulating means is provided.
